Application iled February 8, 1915.

' To all whom t may concern:

Be it known that I, HILLIARD N. A. Mo- LEAN, a citizen of the UnitedStates of America, residing at Detroit, in the county of Wayne and Stateof Michigan, have invented certain new and useful Improvements inSanitary Closets, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention relates to sanitary closets vide a construction in whichthe seat may be'easily and quickly cleaned; to provide a construction inwhich the cleaning of the seat will be automatically accomplished; to

the seat is subjected to a cleaning fluid and then automatically dried.j Other objects of the invention will more fully hereinafter appear.

The invention resides in the peculiar construction, arrangement andcombination of parts as will be hereinafter set forth.

ln the drawings, Figure l is a perspective view of a'closet embodyingthe inveni tion; Fig. 2 is a longitudinal section showing the seat inone position of adjustment; Fig. 3 shows the parts in a differentposition of adjustment; Fig. 4 is a section on the line m-m of Fig. 2;Fig. 5 illustrates a certain relation of parts; Fig. 6 is a top planview;

Fig. 7 illustrates a modification; and Fig. 8 is a section through thecontrolling valve.

A designates the bowl of the closet, and B the seat. The latter isherein shown as composed of a frame C in which are mounted members D andE that form the seat proper. yThese members are mounted to be turned soas to allow different portions of their surfaces to be exposed at thetop, and suitable mechanism is provided for cleaning the surfaces of themembers D and E. The latter are herein illustrated as composed of rollseach carried by a shaft F, the ends of which are journaleol in the endsG and H of the seat frame C. Preferably the frame C is formed of ametallic strip arranged 0n edge except at the front of the bowl, whereit is turned downwardly, as shown in Fig. 1. The frame C is providedwith rearwardly-ex tending arms I that are hinged to brackets J on thebowl, and the front of the frame C is normally held slightly raised fromthe bowl by means of springs D2 on the hinged connection between theseat frame and the bowl.

These springs are of proper tension to allow the seat to be readilydepressed until the frame C rests upon the upper edge of the bowl, asshown in Fig. 5.

For cleaning the seat I preferably subject the surfaces of the rolls toa cleaning liquid and then dry the roll surfaces. Tn the one embodimentof the invention illustrated in Figs. l to 5 inclusive, the frame Ccarries pipes L having perforations M arranged to spray liquid upon theroll surface. These pipes are respectively arranged upon the inner sidesof the rolls and at their rear ends are connected by a swiveled joint Nwith the supply pipe O. Controlling the supply pipe O is a valve P shownherein as ofthe ported rotary type (see Fig. 8). This valve is connectedto a shaft Q, has its outer end arranged in a bracket R, and alsocarrying an arm S.

T is a bell-crank lever fulcrumed at upon a bracket on the bowl andhaving one arm slotted at V to engage a pin XV on the frame C.

X is a spring having one end connected to a pin Y fixed upon the bowland having the `other end attached to a pin Z on the lever S. Thisspring tends to normally hold the level' S in the position shown inFigs. 2 and 3, and ilhe valve in this position is as illustrated in fig. 8.

As will be noted from Fig. S, the port A in the valve proper B-when thevalve is closed-has one end thereof but slightly out of registrationwith the port C in the valve casing. By this arrangement, when the seatrises, the inwardly-extending arm D of the lever T which is above themember S- as shown in Fig. B-will contact with the member S andimmediately1 open the valve B. When theseat is in its raised position,asvshown in Fig. Q, the arm S has passed outof engagement with theinwardly-extending portion D of the lever T, allowing the spring X toclose the valve. However with theparts shown in Fig. 2, when the seat isdepressed the arm S will be raised, but because of the relation of theport A to the port C in the normal position of the valve B', asufficient upward movement of the arm S will be permitted, to allow theextension Dl to pass by the arm S without opening the valve.

In order to allow the surfaces of the rolls to be cleaned, the latterare rotated so that during the time the liquid is sprayed upon therolls, the roll surfaces or portions thereof are cleaned. In thestructure shown, this is accomplished by providing each roll with apinion E that engages a stationary rack F which is secured to the bowl.The racks F may be fastened to the bowl in any desirable manner as bymeans of a metallic strip or frame Gr adapted to fit over the front ofthe bowl and to which the racks F are rigidly connected. Preferably itis desired to turn the rolls during the upward movement of the seat, butto have the rolls remain stationary during the depression of the seat.This is accomplished by connecting thepinion E', through the medium of aratchet mechanism I, to' a member II that is iixed tol turn with theroll but is free to rotate-upon the shaft.

The drying of the roll surfaces is accomplished by means of wipers L andJ pivoted to brackets K carriedby the'frame C and havingthe outer endsthereof yieldably held into engagement with the rolls by means ofsprings M. Preferably the arrangement is such that the rolls are turnedsubstantially half arevolution when the seat is raised from thepositionshown in Fig. 3 to the j position shown in Fig. 2. Because of the fspray pipes are omitted.

relation of the parts, if it is desired, the frame C' and vall themechanism thereon may be raised as a unit to allow access to the bOWl'.

Instead of spraying the liquid upon the rolls, other forms of washingthe rolls may be employed,I and as shown in Fig. 7, another novel andsimple manner of accomplishing this result is illustrated. Thus N arereceptacles carried by the bowl and of a length substantially equal tothe rolls. These receptacles are arranged to allow the rolls to bepartially immersed in the liquid therein whenv the seat is down, butwhen raised the rolls are completely out of the liquid.` In thestructure shownl in Fig. 7, the mechanism for turning the rolls may beaccomplished as hereinbefore described, but the valve operatingmechanismv and the While I have shown and described the particularstructures illustrated in the drawings, I do not wish .to limit theprotection to theseembodiments of the invention, since it will be readlyappreciated that the inven- Copiesl of this patent may be obtained fortion is capable of being used lwith various specific structures.

WhatI claim as my invention is 1. In a closet, the combination with aseat proper composed of rotating portions, of

means for subjecting the rotating portions to a cleaning fluid, andwipers extending longitudinally of said rotating portions and yieldablyheld in engagement therewith.

2. In a closet, the combination with a bowl, of a seat comprising aframe, spaced members mounted in said fralne to turn, means forsubjecting said members to a cleaning fluid, wipers extendinglongitudinally of said members and yieldably held in engagementtherewith, pinions carried by said rolls and stationary racks upon thebowl engaging said pinions, and means for connecting the pinions totheir respective members in one direction of movement of the pinionsonly.

3. In a closet, the combination with `a bowl, of a seat proper composedof coacting rotating portions, of means intimately associated with eachof said portions above said bowl for spraying the same.

4. In a closet, the combination with a seat proper mounted to undergo aslight up and down movement and including rotating portions, of meansfor moistening said portions, and means for automatically rotating saidportions during its slight upward movement, said portions beingstationary during the downward movement.

5. In a closet, the combination with a seat comprising a frame mountedto undergo a slight up and down movement and a pair of parallel rollersmounted in said seat, of a mechanism utilizing said movement of saidframe to actuate a simultaneous rotation of the rollers, means fordischarging a liquid upon said rollers, and a valve controlling thesupply of liquidrto said discharge means, normally closed, automaticallyopened by a displacement ofl said frame and automatically closing assaid displacement is completed.

In testimony whereof I affix myrv signature in presence of twowitnesses.
